CD54HC221 Monostable Multivibrator

CD54HC221 Monostable Multivibrator Series Datasheet

The TEXAS INSTRUMENTS (TI) ’HC221 and CD74HCT221 are dual monostable multivibrators with reset. An external resistor (RX) and an external capacitor (CX) control the timing and the accuracy for the circuit. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q terminals. Pulse triggering on the B input occurs at a particular voltage level and is not related to the rise and fall time of the trigger pulse.
